__________ is a protein that is carried by red cells. It picks up oxygen in the lungs and delivers it to the peripheral tissues to maintain the viability of cells. It is made from two similar proteins that "stick together". Both proteins must be present for it to pick up and release oxygen normally. One of the component proteins is called alpha, the other is beta. Before birth, the beta protein is not expressed. A variant of this protein found only during fetal development, called gamma, substitutes up until birth.
Correct Answer
hemoglobin, HemoglobinExplanation
HEMOGLOBIN - Like all proteins, the "blueprint" for hemoglobin exists in DNA (the material that makes up genes). Normally, an individual has four genes that code for the alpha protein, or alpha chain. Two other genes code for the beta chain. (Two additional genes code for the gamma chain in the fetus). The alpha chain and the beta chain are made in precisely equal amounts, despite the differing number of genes. The protein chains join in developing red blood cells, and remain together for the life of the red cell.Rate this question:

Leukocytes are white blood cells that protect the body in various ways against disease.
- A.
True
- B.
False
Correct Answer
A. TrueExplanation
The statement is true because leukocytes, also known as white blood cells, play a crucial role in the body's immune system. They help to defend the body against infections, diseases, and foreign substances by identifying and destroying pathogens. Leukocytes are responsible for the body's inflammatory response, phagocytosis, and the production of antibodies. Their presence and activity are essential for maintaining overall health and protecting the body from various illnesses.Rate this question:

Red blood cell
- C.
Erythrocyte
Correct Answer(s)
B. Red blood cell
C. ErythrocyteExplanation
The red blood cell, also known as an erythrocyte, is the most numerous cell in the body. These cells are responsible for carrying oxygen to all the tissues and organs in the body. They make up about 40-45% of the total blood volume and are constantly being produced and replaced in the bone marrow. White blood cells, on the other hand, are involved in the immune response and are much less numerous than red blood cells.Rate this question:

Note the bi-concave shape...almost like a donut.
From Wikipedia (Erythrocytes)...
These are red blood cells the most common type of blood cell and the vertebrate organism's principal means of delivering oxygen (O2) to the body tissues via the blood flow through the circulatory system.
They take up oxygen in the lungs or gills and release it while squeezing through the body's capillaries.
These cells' cytoplasm is rich in haemoglobin, an iron-containing biomolecule that can bind oxygen and is responsible for the blood's red color.
In humans, mature red blood cells are flexible biconcave disks that lack a cell nucleus and most organelles. 2.4 million new erythrocytes are produced per second.
The cells develop in the bone marrow and circulate for about 100–120 days in the body before their components are recycled by macrophages.
Each circulation takes about 20 seconds. Approximately a quarter of the cells in the human body are red blood cells.Rate this question:

Correct Answer
C. PlateletExplanation
Platelets are small, colorless cell fragments that play a crucial role in blood clotting. They are formed in the bone marrow and are essential for preventing excessive bleeding by forming clots at the site of injury. Platelets help to seal off damaged blood vessels and promote the formation of a stable blood clot. Unlike red and white blood cells, platelets do not have a nucleus and are much smaller in size. Therefore, the correct answer is platelet.Rate this question:

- A.
RBC
- B.
WBC
- C.
Platelet
- D.
Plasma
Correct Answer
C. PlateletExplanation
Platelets are tiny cell fragments that are essential for blood clotting. When there is an injury or damage to blood vessels, platelets rush to the site and form a plug to stop bleeding. They release chemicals that attract other platelets and help in the formation of a stable blood clot. Platelets also contain proteins that aid in the repair and healing of damaged tissues. Therefore, platelets play a crucial role in the clotting process and are responsible for preventing excessive bleeding.Rate this question:

Correct Answer
C. KidneyExplanation
The kidney is responsible for cleaning and filtering the blood. It removes waste products, excess water, and toxins from the bloodstream, producing urine as a result. The kidneys play a vital role in maintaining the body's overall balance by regulating electrolytes, pH levels, and blood pressure. The heart pumps blood, the liver processes nutrients, and the bladder stores urine, but it is the kidney that specifically cleans and filters the blood.Rate this question:
