Study Notes
Blood Composition and Function
- Copper is present in the hemoglobin of octopuses, which gives it a blue-green color.
- Iron gives the red color to the blood in humans and some other animals.
Octopus Physiology
- An octopus has three hearts.
Unusual Blood Colors
- The sea cucumber has green-colored blood due to the presence of a green pigment called bilin.
- Some invertebrates, such as starfish and sea urchins, have colorless blood.
Blood Components
- Plasma is the liquid portion of the blood that makes up about 55% of its total volume, and its main function is to transport proteins, nutrients, hormones, and gases throughout the body.
Serum vs. Plasma
- Serum is the liquid portion of the blood that remains after blood has clotted, whereas plasma is the liquid portion of the blood before clotting.
- The main difference between plasma and serum is that plasma contains clotting factors, which are removed during the clotting process to form serum.
Non-Protein Nitrogen (NPN) Compounds
- NPN compounds, such as urea, uric acid, and creatinine, are waste products in the blood that are transported to the excretory organs for removal.
Erythrocyte Function
- Erythrocytes, also known as red blood cells, play a crucial role in mammals by carrying oxygen from the lungs to the body's tissues and carbon dioxide from the tissues to the lungs.
Homeostasis
- Maintaining homeostasis in extra-cellular fluid is essential to ensure proper cellular function, as it helps regulate pH, temperature, and the balance of essential ions and nutrients.
