Q7. Where in the body would you find sinusoidal capillaries?a) Brainb) Kidneyc) Spleend) Skeletal muscle

Breakdown of the Problem

1. Identify the types of capillaries found in different organs.
2. Understand the characteristics of sinusoidal capillaries.

Relevant Concepts

• Sinusoidal Capillaries: These are specialized capillaries that have larger openings than regular capillaries, allowing for the passage of larger molecules and blood cells. They are commonly found in organs where extensive exchange of substance occurs.

Analysis and Detail

1. Brain: Has continuous capillaries, which are tightly packed to form the blood-brain barrier.
2. Kidney: Primarily contains fenestrated capillaries for filtration processes.
3. Spleen: Contains sinusoidal capillaries; these capillaries allow for the exchange of blood cells and proteins.
4. Skeletal Muscle: Contains continuous capillaries which are standard for muscular tissues.

Verify and Summarize

From the analysis, the organ where sinusoidal capillaries are primarily found is the spleen.

Final Answer

c) Spleen
