Circulatory System

Levels of Organization
Body system
Cardiac Cell
Cardiac muscle cells have a high mitochondrial density, which allows them to produce adenosine triphosphate (ATP) quickly, making them highly resistant to fatigue

Cardiac Tissue
Cardiac muscle is only found in the heart and makes up the bulk of the heart’s mass.

Human Heart
A man’s heart weighs about 10 ounces, while a woman’s heart weighs approximately 8 ounces.
Cardiovascular system
If you were to lay out all of the arteries, capillaries and veins in one adult, end-to-end, they would stretch about 60,000 miles. An adult human has an average resting heart rate of about 75 beats per minute, the same rate as an adult sheep.

Organism
If temperature rises the flow of blood into vessels in the skin increases. If the temperature drops the flow of blood to the skin is restricted. The circulatory system helps deliver oxygen throat the body.
homeostasis
How the circulatory help the body mantain homeostasis
By circulating blood and other cells the circulatory system suppiles nutrients, energy, protection & a myriad of other things throughout the body to control the balance

Thrombocythemia. is when your bone marrow makes too many platelets. People with thrombocythemia may have platelet counts that exceed 1 million. Symptoms can include blood clots that form and block blood supply to the brain or the heart. This is because your platelet count cannot maintain balance which disrupts homeostasis.

Interaction
Lymphatic system- Every time your hearts pumps, a little fluid is forced out of the thin walls of the tiniest blood vessels called capillaries. Most of this fluid is reabsorbed by the capillaries and the remaining fluid is absorbed by the lymph capillaries.
Respiratory system- The lungs hold air that is breathed in. Oxygen in the air moves into the blood. The heart pumps to transports this oxygenated blood to cells in the body that need it to produce energy.
Endrocrine system- The two adrenal glands are at the top of the kidneys. Each adrenal gland has an outer region called the cortex and an inner one called the medulla. The medulla secretes adrenaline into the blood stream and the cortex secretes steroid hormones. Adrenaline has the effect of increasing blood pressure and heart rate
