My answer

HUMAN CIRCULATORY SYSTEM

Human circulatory system is responsible for flow of blood , nutrients , oxygen and other gases , hormones and drugs to and from cells . It consist of heart , blood , lungs, arteries , veins , capillary , coronary and portal vessels.

Heart: It is a muscular organ and is located behind and slightly left of breast bone of rib cage . It contains four Chambers , two atria and two ventricles. It pumps blood through the network of arteries and veins called the cardiovascular system.

Lungs: pulmonary arteries carry deoxygenated blood to the lungs , where carbon dioxide is released and oxygen picked up during respiration.

Veins: They carry deoxygenated blood from all parts of body to heart .

Arteries: They carry oxygenated blood from heart to all parts of body.

Portal vessels: carry blood from gastrointestinal tract , gall bladder , pancreas and spleen to liver.

Coronary vessels: coronary arteries supply oxygenated blood to the heart muscle . Coronary veins drain deoxygenated blood from it.

Capillary : They carry blood between arterioles and venules.

Blood: It is a body fluid that delivers necessary substances such as nutrients and oxygen to cells and transport metabolic waste away from cells.

Parasympathetic and sympathetic system control heart rate . Through these system body reacts to it's internal and external environments to change heart rate and maintain homeostasis .For instance take the case , when a person starts to exercise , body stops parasympathetic stimulation of heart , so the rate can increase , bring more oxygen and nutrients to muscles. As the exercise rate increases sympathetic system begin sending signals to the heart to raise rate even more. As a measure of maintaining homoeostasis increased rate of waste products are removed.

Respiratory diseases are one of the major diseases found in the inhabitants of Saudi Arabia. Asthma, lung cancer , tuberculosis ,chronic obstructive pulmonary disease are prevalent. Cardio vascular diseases like hyper tension and fluctuation in blood pressure are also prevalent.

in 350 words, What is the adaptive value of dark skin tones in equatorial regions such as Africa? What evolutionary pressure caused a lightening of skin tones away from this area?

Under "GI Disorders" choose an area of the bowel or perhaps "Kids and Teens". Choose a bowel area and then a specific pathology.

Investigate a bowel pathology.

Include the following aspects in the assignment:

·         Summarize the pathology

·         Include signs and symptoms, tests/diagnostics, treatments, and outcomes

·         Explore the other tabs across the top of the IFFGD site and share what you found most interesting: Manage Your Health, Resources, News, and Research

·         There is no word limit for this assignment but you must thoroughly address each bullet point.

Humans are bipedal, terrestrial omnivores. As a species, we are adapted to quite a range of habitats, from deserts to mountains and from rain forests to tundra. Your job is to determine how humans might be adapted to live in a low gravity environment (half of Earth's gravity).

Write a brief description of the musculoskeletal system of a human that adapted to your environment, and why it would look the way it does. Consider the following:

• What would be required to support and move the body, and to support their lifestyle? You are encouraged to look up other (non-human; can be non-mammalian) animals that share these habitats for ideas.
• What if humans had evolved and were adapted to live in very specific habitats? In other words, it would still look *basically* like a human but would have some important differences related to its circulatory and/or breathing systems.
• What would these systems of a human that adapted to a different environment look like, and why would it look like this?
• You should consider the following parts of the musculoskeletal system in your answer: Bone length, Bone diameter, Bone density, Muscle type, location, and size, Anything else you think is important to the musculoskeletal system.
