The center of the circulatory, or cardiovascular system, is the heart, a powerful pump organ designed to beat many millions of times over the lifetime of an organism. The heart circulates blood throughout the veins and arteries. Arteries carry oxygen-rich blood away from the heart, providing it to tissues, then returning the depleted red bloods cells back to the heart through the veins for reoxygenation. Blood flows from your right atrium into your right ventricle through the open tricuspid valve.When the ventricles are full, the tricuspid valve shuts. This prevents blood from flowing backward into the atria while the ventricles contract (squeeze). blood leaves the heart through the pulmonic valve, into the pulmonary artery and to the lungs.The pulmonary vein empties oxygen-rich blood, from the lungs into the left atrium. blood flows from your left atrium into your left ventricle through the open mitral valve. When the ventricles are full, the mitral valve shuts. This prevents blood from flowing backward into the atria while the ventricles contract (squeeze). blood leaves the heart through the aortic valve, into the aorta and to the body. This pattern is repeated over and over, causing blood to flow continuously to the heart, lungs and body.

Rats can not regulate their body heat. Most mammals can regulate their body heat when their blood is high enough.

Yes, blood plays a crucial role in regulating the body by transporting oxygen, nutrients, hormones, and waste products throughout the body. It also helps to regulate temperature, pH balance, and immune response.
Sodium is the mineral that helps regulate water in the body's blood and tissue. It plays a key role in maintaining fluid balance and regulating blood pressure.
the Precapillary Sphincters control blood pressure and body temperature by regulating the flow of blood to the capillary bed.
The kidneys regulate fluid in the body to maintain proper balance of electrolytes, fluid volume, and blood pressure. This helps in filtering waste products from the blood and maintaining overall body function. Failure to regulate fluid balance can lead to dehydration or fluid overload, causing health issues.
The renal system helps regulate fluid balance, electrolyte levels, and blood pressure in the body. It filters waste products from the blood to create urine, which is then excreted from the body. Additionally, the kidneys play a key role in maintaining acid-base balance and producing hormones that regulate red blood cell production and blood pressure.
Homeostasis!
They are called "hormones".
