Art-labeling Activity: The Composition of Whole Blood Part A Drag the labels to identify the constituent parts of blood. Famed elements Plasma Red blood cells Water Other solutes Platelets Plasma proteins 46-67% 37-54% Reset Help 1 of 7
The Correct Answer and Explanation is:
Here is the correct answer for the activity:
- Formed elements – Includes red blood cells, white blood cells, and platelets, collectively making up about 37-54% of the blood volume.
- Plasma – The liquid portion of blood, accounting for approximately 46-67% of the total volume.
- Red blood cells – The most abundant cells in blood, responsible for oxygen transport.
- Water – Constitutes around 90% of plasma, serving as the medium for solutes and cells.
- Other solutes – Includes electrolytes, nutrients, gases, and waste products, making up about 1-2% of plasma.
- Platelets – Small cell fragments essential for blood clotting, found within the formed elements.
- Plasma proteins – Comprise albumin, globulins, and fibrinogen, supporting immune functions, osmotic balance, and clotting.
Explanation: Blood is a vital fluid circulating through the body, performing essential functions such as nutrient transport, oxygen delivery, and immune defense. It is composed of two main components: formed elements and plasma. Formed elements include red blood cells, white blood cells, and platelets, contributing to about 37-54% of blood volume. Red blood cells transport oxygen via hemoglobin, while platelets aid in blood clotting to prevent excessive bleeding. White blood cells defend against infections, though they are not explicitly labeled in this exercise.
Plasma constitutes 46-67% of blood volume and serves as the medium for transporting various substances. It primarily consists of water, which allows nutrients, hormones, and gases to dissolve and travel efficiently. Plasma proteins play a role in maintaining osmotic pressure, supporting immune function, and aiding in clot formation. Other solutes, including electrolytes, help regulate pH balance and cellular activity.
This composition ensures proper physiological function, maintaining equilibrium in the circulatory system. Understanding blood components is fundamental for fields such as medicine and biomedical research, as abnormalities can indicate health disorders such as anemia or clotting deficiencies. Analyzing blood properties allows medical professionals to diagnose and treat conditions effectively.
