What is anatomy
Anatomy is the biological structure of every living organism
What is physiology
Physiology is the science features of the human body human body is made up of biological systems. That create the composite structure of a human being. Circulatory system system has three sub-systems, heart, lungs and arteries/veins, portal vessels system. The main functions are To convey oxygen, carbon dioxide, blood, growth body hormones and nutrients around the body .
Aorta
largest artery in the body, made up of three layers the intima, the media and the adventitia. It takes blood away from the heart to the organs, via the hearts muscular pumping chamber in the left ventricle. This pumps blood into the aorta through the aortic valve.

Arteries take oxygenated blood away from the heart to cells, veins take blood through the super vena cava which is low in oxygen to the heart
Digestive system system regulates what you put into your body. Taking out the rich nutrients, minerals, vitamins and chemicals, then transporting these to the correct body parts. It also excretes the waste products in the format of urine, excrement and sweat. gastrointestinal tract.
Enzymes in the saliva break down starches. This makes the food easy to digest, vital nutrients are absorbed through the capillaries in your inner cheek. This is why it's important to chew your food pharynx main function is to determine whether food or oxygen is going in the windpipe. This is where a small layer of skin called the epiglottis sits. This seals of the windpipe when eating, preventing you from inhaling food
Oesophagus
joins the pharynk to the stomach ,the lower oesophagus sphincter a ring like muscle, opens up to let food into the stomach. It also stays closed to prevent food retuning from the stomach.
Stomach
stomach. Once in the stomach, peristalsis ensures that the food mixes with digestive juices

Here it gets broken down even further in the duodenum this is the first part of the lower intestine then u have the jejunum and ileum
Large intestine
Where u have the appendix, cecum, and colon, Here the waste products consist of undigested food, foreign matter, water and old cells from the gastrointestinal tract .the large intestine converts the liquid state to a solid state called stools. peristalsis pushes this towards the rectum
Rectum
where it is stored until u go toilet and it is deposited out of the anus, During bowel movement.
The respiratory system
The respiratory systems primary functions is to inhale oxygen into the lungs, exhale carbon dioxide out. nasal cavity main route for oxygen to enter the body. More effective than the mouth which has no protection and does not warm the air. The nose is made of bone cartilage with a mucus membrane and nostril hairs to filter out any foreign particles like dust.
Pharynx
pharynk sits in the back region of the nasal cavity, The pharynk muscles contain four layers the external, superior, middle and the inferior constrictor muscles. The main function of the pharynk is to determine whether food or air are passing through.
TASK 3.1 Write a report comparing and contrasting the structure and function of the three types of blood vessels. The Structure and Functions of Blood Vessels ARTERIES The walls of arteries contain smooth muscle fibre that contract and relax under the instructions of the sympathetic nervous system. The functions of the arteries are: transport blood away from the heart and transport oxygenated blood only.
The kidneys of the fetal pig can be located on both sides of the spine behind the abdominal organs. The kidneys’ are a vital part in the process of removing urine from the body. The path that urine takes to exit the body is very specific. First, the urine is in the kidney. Next, the urine goes into the ureters, followed by the bladder and urethra before exiting.
The proper functioning of one system relies on the proper functioning of the other system. In other words, the digestive system needs to be in good working order to support the functions of the cardiovascular system. An example of the digestive and cardiovascular systems interrelating is: the first step in digestion of fat is to dissolve it into the intestine where bile acids produced by the liver dissolve the fat into fatty acids and cholesterol. The bile acids join with the fatty acids and cholesterol and vessels then carry the changed fat to the veins of the chest, and the blood carries the fat to storage in different parts of the body.
This organs help get rid of the wastes from the body as either urine or
Homeostasis is the body's method of keeping internal stability no matter what external influence disturbs its normal functioning (Anna, 2011). And the respiratory system is one of the systems in the body that helps to maintain homeostasis by maintaining pH and regulating gas exchange. The main function of this system is take in oxygen and get rid of carbon dioxide. This system has external respiration and internal respiration. External respiration is a mechanical process that exchange of gases in and out of the body, while internal respiration is the chemical process that breaking down nutrients with oxygen to produce energy.
Mod 10 Health/Wellness Assignment Name: Vedat Ulas Date: 11/6/15 Please find the following questions in your textbook: 1) Page B7, #1-5 1. Explain how the body is organized. The body is organized by the skeletal system the muscular system the nervous system digestive system the circulatory system and the respiratory system all of these systems are organized with cells, and tissue these make our organs and makes our systems.
The digestive system is responsible for chemically and mechanically breaking down food and includes organs such as, mouth, esophagus, stomach, small intestine, rectum, anus, and additional accessory organs. These organs all aid in the breakdown of food. Food is broken down mechanically by chewing and churning in the stomach, and chemically by acidic enzymes in the stomach and in the small intestine which receives enzymes from the pancreas that are specifically designed for the breakdown of nutrients. Once the food and nutrients are broken down, the excretory system removes whatever the body decides is waste by filtering blood in the nephrons of the kidneys and turning it into urine which is then collected in the bladder and removed from the body when the bladder is
Once the food has been chewed into a small soft mass called bolus, deglutition (swallowing) process takes place. The tongue helps to move and push the bolus into the back of throat then enters the esophagus (a hollow muscular passage that allows food bolus to travel from throat to the stomach). The second step is peristalsis. Food bolus does not just free-fall into stomach yet, as a
There is also strong acid released by the glands in the lining of the stomach which helps break down food into a more useable form and also aids in the destruction of most ingested bacteria. After the contents have successfully been broken down they are released into the small intestine. The small intestine is a 22 foot long tube that helps to break down the food with enzymes released from the pancreas and bile released form the liver. In this organ the process of Peristalsis is at work, pushing the food further and further through the small intestine towards the colon. These movements are stimulated by the presence of chyme.
The muscular system might be the most important system in the whole entire body. This system helps us digest food and keeps our heart and lungs moving. In the body there are two different types of muscles: the voluntary and involuntary. The muscular system helps you move because it helps your joints move which helps your bones bend. All of the major organs in this system are the heart, the lungs, and the digestive tracks.
The jejunum is the part of the entire GI tract where the most absorption of nutrients occurs (McCauley, Kong et al. 1999). Last part of the GI tract is the ileum wherein there is some important absorption of nutrients that takes place e.g. absorption of Vitamins etc. The busiest part of the small intestine is the duodenum because there are bunch of things that are involved in
The human body is an amazing thing made up of many different parts. These parts are cells, tissues, organs, and organ systems. For starters, one type of cell makes up one type of tissue. Next, two or more types of tissues make an organ. Then, a few organs working together make an organ system.
The nerve supply also comes from her celiac plexus innervating the liver mixture of sympathetic and parasympathetic fibers. These ribs reach the liver by the hepatic artery. Liver Physiology The liver performs many functions in the body such as: • Production of bile: The liver excretes bile to the bile duct and thence to the duodenum. Bile is necessary for digestion of food.
The Cardiovascular System (Known as circulatory system) is an important system within the human body which functions with specific organs such as the heart, blood vessels – including capillaries, veins, and arteries along with small blood vessels, and blood. The cardiovascular system works by your inhaling process. As you inhale, the air goes towards your lungs. Since the air contains oxygen, your blood stream absorbs this through your lungs.
This is how the process of digestion and absorption of nutrients takes place the food enters
