Circulatory System

The circulatory and digestive systems work together to ensure that mammals survive by facilitating nutrient absorption and distribution. The digestive system breaks down food into essential nutrients, which are then absorbed into the bloodstream via the intestinal walls. The circulatory system transports these nutrients to cells throughout the body, providing the energy and building blocks necessary for growth, repair, and overall functioning. Additionally, the circulatory system helps remove waste products produced during digestion, maintaining internal balance and health.

The arterioles are most responsible for determining systemic vascular resistance. And small ateries and Venules are also act as resistance vessels.

Resistance vessels react to the sympathetic and nervous regulations .
When sympathetic n. s. is excited blood vessels constricted and blood floor reduced. Its a method of heat saving in cold weather.

The kidneys would secrete elevated amounts of erythropoietin.

Yes it would be a heart cancer or cancer in the vains

The human respiratory system contains two lungs, symmetrically arranged in the chest, the trachea, which leads from the lungs to the mouth and nose. This simple arrangement allows humans to breathe.

Blood flows from the heart to the arteries and then from the arteries to the

the systemic and pulmonary circulation

The circulatory system (which is comprised of your lungs, heart, arteries, capillaries, and veins) is the system which distributes blood (and therefore oxygen) through out the body.

The heart and blood vessels are the main organs of the circulatory system. The lungs are part of the respiratory system.

When an injury involving bleeding occurs, your platelets stick to one another and help stop the flow by making scabs and begin healing the wound.

your heart has a artery that pumps through the lung and takes out the carbon dioxide which you brath out and replaces it with oxygen that you inhale.

Lymphatic System

the circulatory system carries all the oxygen you breathe in and give it to the muscular system. that way, it can function correctly adn keep your body healthy. also, without muscles, the heart wouldn't function since it is a cardiac muscle.

False.

Stroke Volume (SV) = EDV - ESV

(EDV) Ending Diastolic Volume

(ESV) Ending Systolic Volume

a hormone.

because the exertion increases the blood pressure and the pulse rate of the person maybe causing him heart failure

Most likely. I dont know for a fact, but most living things have a circulatory system. Id be suprised if thay dont. The circulatory system is needed in most living things.

some worked hard but others had no initiative, without everyone benifiting but few contributing, the food suply ran out :)

The protein haemoglobin found in red blood cells binds reversibly with oxygen. It is the oxygen transporter in blood, and when combined with oxygen the product is oxyhaemoglobin. One haemoglobin molecule binds with four oxygen molecules in accordance with the chemical equation:

Hb + 4O2 -> Hb(O2)4

Note: Hb is haemoglobin; Hb(O2)4 is oxyhaemoglobin
