Human Body System Research Paper

The patient’s autonomic nervous system would react to the arrow attack by activating the sympathetic and parasympathetic nervous system. The brain sends a stress signal throughout the body and the hypothalamus activates the sympathetic nervous system by sending signals through the autonomic nerves to the adrenal glands. These glands respond by pumping the hormone epinephrine, also known as adrenaline into the blood. Epinephrine starts to go throughout the body, the heart starts to beat faster-pushing blood to the muscles, heart, and other organs. Your pulse and blood pressure go up, and you will start to breathe more rapidly.

The purpose of homeostasis is the maintaining of an equilibrium (balance) inside the body. In other words it is how the human body responds to it’s environment. It is a constant process occurring in our bodies, for example when we eat, drink or exercise our body composition, which refers to the percentages of fat, bone and water in the body, and how they remain exactly the same. The key components of the homeostatic system are the receptor/ sensor, control centre, variable and the effector. The receptor is the sense organ that detects the change, the control centre is usually the brain or a certain section of the brain, and the effector, which produces the response to counteract the change.

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.

Explain how cells are important to tissues. Cells are important because cells are formed to make tissue. Another reason is cells in a tissue work together to do a specific job. 4. Synthesize how might the digestive system and the circulatory system work together?

From the synaptic cleft, the ACh binds to the receptors located on the muscle fiber’s plasma membrane. After the ACh has found its way to the receptors and is bound to them, the muscle fibers become stimulated. The stimulated muscle fibers result in an impulse being generated. This impulse travels down the membrane until it reaches the Sarcoplasmic Reticulum. The Sarcoplasmic Reticulum is responsible for regulating the Ca2+ ion concentration.

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.

Endomysium is found within a muscle and it contains nerves and capillaries. It is a fine layer of connective tissue that extracts each individual myocyte. P5 – Describe the sliding filament theory, giving a step by step process.

The functions of the human cardiopulmonary system can be broken down into two, circulatory system and the respiratory system. The main goal of these two systems is to maintain homeostasis in our body. Homeostasis can be described as a type of condition where the internal continuity of an individual has to keep steadiness, regardless of any external changes from the outside environment. External changes from the outside environment may include factors such as excitement, stress, exercise, diet, and much more. Exercise can be carried out because the human body can endure a high level of exercise during a prolonged period of time.

Sympathetic nervous system is the one that will be engaged. This is because; sympathetic nervous system normally functions to produce reflex adjustments and localized adjustments of the cardiovascular system. Under conditions of stress, activation of the entire sympathetic nervous system occurs producing the fight-or-flight response. What characterizes this response is an increase in heart rate, epinephrine release from the adrenal gland in large quantities, vasodilation of the skeletal muscle, cardiac output increase, vasoconstriction of cutaneous and gastrointestinal, dilation of pupillary piloerection and bronchial dilation. Preparing the individual for imminent danger is the overall effect (Bechir 2010).

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
