Study Notes
Heart and Blood Vessels
- Heart functions as a pump to circulate blood throughout the body, providing oxygen and nutrients necessary for cellular metabolism.
- Blood vessels, including arteries, veins, and capillaries, facilitate the movement of blood, linking the heart with all body tissues.
Function of Blood
- Blood serves as a transport medium carrying oxygen from the lungs to cells and carbon dioxide from cells back to the lungs.
- It delivers essential nutrients absorbed from the digestive system to various body parts.
- Hormones and waste products are also transported through blood, playing crucial roles in maintaining homeostasis.
Transport Mechanisms in Blood
- Blood contains red blood cells that bind to oxygen (via hemoglobin) for delivery to tissues, while returning carbon dioxide to the lungs.
- Plasma, the liquid component of blood, carries nutrients, hormones, proteins, and waste materials dispersed throughout the body.
Response to Cuts
- When an animal experiences a cut, blood vessels constrict to reduce blood loss (vasoconstriction).
- Platelets aggregate at the site of injury, forming a clot to seal the wound, preventing excessive bleeding and pathogen entry.
Circulatory System Role
- The circulatory system is essential for distributing oxygen, nutrients, and hormones, while facilitating waste removal from tissues.
- It regulates body temperature and pH balance, contributing to overall homeostasis.
- The circulatory system includes the heart, blood vessels, and blood, working together to ensure adequate nutrient and oxygen supply across the organism.
