What is the function of Plasma in Blood?

Plasma is the liquid part of blood that carries cells, nutrients, hormones, and waste products.

What is the role of Hemoglobin?

Hemoglobin is a protein in red blood cells that binds to oxygen, enabling its transport throughout the body.

What is the purpose of Capillaries?

Capillaries are tiny blood vessels that connect arteries and veins, allowing for nutrient and gas exchange with tissues.

What is the process of Circulation?

Circulation is the movement of blood through the heart and vessels, delivering oxygen and nutrients to cells and removing waste.

What is the role of the Liver in Excretion?

The liver processes nutrients and detoxifies substances, producing bile that aids in digestion and waste removal.

What are Nutritional Needs?

All organisms need food, water, and oxygen for survival, necessitating the transport of these substances for various bodily functions.

What is the Circulatory System?

The system responsible for transporting nutrients, oxygen, and waste through blood, facilitated by the heart and blood vessels.

What is Blood Composition?

Blood consists of plasma and various cell types, including red blood cells (RBC), white blood cells (WBC), and platelets.

What are Red Blood Cells (RBC)?

Cells that contain hemoglobin which binds with oxygen and are essential for efficient oxygen transport to all cells.

What are White Blood Cells (WBC)?

Cells involved in the immune response against germs.

What are Platelets?

Cells involved in blood clotting, forming clots to plug cuts and injuries.

What are Arteries?

Blood vessels that carry oxygen-rich blood away from the heart; they have thick elastic walls to withstand high pressure.

What are Veins?

Blood vessels that carry carbon dioxide-rich blood back to the heart; they have thinner walls and valves to prevent backflow.

What is Heart Functionality?

The heart is a muscular organ that pumps blood continuously, divided into four chambers: two atria and two ventricles.

What is Excretion?

The process of removing waste substances from the body, primarily performed by the excretory system.

What are Kidneys?

Organs that filter blood, remove waste, and produce urine.

What is Xylem?

Vascular tissue in plants responsible for transporting water and minerals from roots to leaves.

What is Phloem?

Vascular tissue that transports food produced by leaves to other parts of the plant.

What is Ammonia?

Waste product excreted directly into water by aquatic animals.

What is Uric Acid?

Semi-solid waste product excreted by birds.

What is Urea?

Waste product excreted by land animals, including humans.

What is Transpiration?

The process in plants that causes water loss, creating suction that aids in the upward movement of water.
