The flow of oxygenated blood to the tissues helps deliver nutrients such as amino acids and electrolytes, water and oxygen. Also, it’s responsible for removing metabolic waste from the cells and disposing of carbon dioxide. The cardiovascular system’s anatomy varies throughout the body and is connected by the arteries, veins, and capillaries. The main organ of the cardiovascular system is the heart. It 's located in the upper torso, chest area, as are some of the body 's major blood vessels.
P4 – Describe the three structures of the skeletal muscle (Epimysium, Perimysium and Endomysium) There are three structures of the skeletal muscle: Epimysium is a thick layer of irregular connective tissue that pulls the entire muscle as well as protecting the muscle from friction that may be caused by other muscles and bones surrounding them. Also, it is the fibrous tissue which covers and surrounds skeletal muscles. The Epimysium carries on past the end of bones in order to create muscle tendons. Perimysium surrounds a bundle of muscle fibres, it is a casing of connective tissue. Endomysium is found within a muscle and it contains nerves and capillaries.
The musculoskeletal system is a complex arrangement of bones, muscles, cartilage, tendons, ligaments, joints, and other connective tissue. This system provides form, support, stability, and movement for the body. It is comprised of two separate systems, the skeletal system and the muscular system. Both of these systems are vital for the body to be able to function properly. For instance, the skeletal system protects and supports the weight of the body’s organs, serves as storage for calcium and phosphorous, and contains critical components for the production of blood.
The ventricles are the discharged chambers. This is how the blood is pumped out of the heart. When the chambers contract, the blood goes out of the heart and into circulation. Circulation is the movement of fluids
Then, a few organs working together make an organ system. Each of the organ systems in your body have a certain function, or job. Working together, all of these organ systems make up an organism. In other words, cells make up tissues, tissues make up organs, organs make up organ systems, and organ systems make an organism. To begin with, cells are the basic unit of life.
Veins transport blood to the heart and lungs at low pressure after receiving it from the capillaries. Valves inside the veins keep blood moving in one direction. The human body's arterial system branches out from one main artery, the dorsal aorta. Like veins, arteries have three layers: an outer layer of tissue, an inner layer of epithelial cells and a layer of muscle in between. Arteries deliver oxygenated blood to the capillaries, where the exchange of oxygen and carbon dioxide takes place.
Human body consists of several types of body systems that perform in collaboration with one another in sustaining a person’s health and life. Body system is defined as a complete framework that forms by multiple organs which work together in maintaining body function (Chiras, 2013). The main system in our body is categorized into three important systems namely respiratory system, cardiovascular system and urinary system (refer to Figure 1 in Appendix 1). One of the main body systems is the respiratory system. Respiratory system consists of two tracts which are the upper respiratory tract comprising only the conducting portion which transports air to and from lungs and the lower respiratory tract that includes both the conducting portion
The adult human skeletal system consists of 206 bones, as well as a network of tendons, ligaments and cartilage that connects them. The skeletal system performs vital functions; support, movement, protection, blood cell production, calcium storage and endocrine regulation that enable us to survive. Below are more details on the exact role the skeletal system has on; protection, shape, support, movement and blood production:
Stratum Lucidum III. Stratum Granulosum IV. Stratum Spinosum V. Stratum Basale 1.2.2. Dermis It is middle layer which contain connective tissue, sweat gland, hair follicles, collagen, blood vessels, nerves and various glands. Function of dermis layer is to provide strength, elasticity and to cushion the body stress and strain.
It works with: • The Skeletal System: it provides calcium that the brain needs, the skull protects the brain, the vertebrae protect the spinal cord, sensory receptors in joints between bones send signals about body position to the brain, and the brain regulates the position of bones by controlling muscles. • The Circulatory System: the heart brings blood to the brain, it sends information to the brain about blood pressure, cerebrospinal fluid flows into the blood supply, and the brain regulates heart rate and blood
The PNS contains somatic nervous system and the autonomic nervous system. The autonomic nervous system controls the function of internal organs like your heart, stomach, cardiac muscle, and your glands. The autonomic nervous system has an effect on the organs, muscles, and glands are all done voluntary. The autonomic nervous system can change the body temperture, send extra blood to a particular area, slow your heartbeat, and pull the stomach secretion. The somatic nervous system is made up of sensory organs and nerves that connects to the skin, also that connects to all the skeleton muscles.
The pons are a part of the metencephalon in the hindbrain. The medulla oblongata is located between the pons and spinal cord. This structure is responsible for basic vital life functions such as breathing, heartbeat, and blood pressure. The midbrain is involved in functions such as vision, hearing, eye movement, and body movement. The pons are involved in motor control and sensory analysis.
The nervous system has many significant functions such as direction of your movements, focusing of the eyes, pain sensory, contraction of the muscles allowing your heart to pump sending blood and oxygen to all your vital organs and removing harmful toxins. Your brain is the control centre of the body. The most largest and complex part of the brain is the cerebrum, the centre of learning. This controls the way you use language, feel emotions and think. It is divided into two sides which are connected together by nerve bundles called the corpus callosum.
