Step 1

The circulatory system is responsible for transporting blood and lymph through its network of arteries and veins. It is a closed system. On the other hand, the lymphatic system is an open system that filters out pathogens in the body. Show more…

Key Concepts

Capillaries

Capillaries are the tiny, thin-walled blood vessels that facilitate the exchange of oxygen, nutrients, and waste products between the blood or lymph and surrounding tissues. Both the circulatory and lymphatic systems utilize capillaries to promote this critical exchange process.

Lymphatic System

The lymphatic system is a network of vessels and nodes that transport lymph, a fluid containing white blood cells, throughout the body. It plays a key role in immune function by filtering pathogens and waste products and operates as an open system, meaning it eventually drains back into the circulatory system.

Circulatory System

The circulatory system consists of the heart, blood vessels, and blood. It functions as a closed system, continuously circulating blood to transport oxygen, nutrients, and waste products throughout the body, and includes structures such as arteries, veins, and capillaries.

00:01 Hey everybody today we're talking about lymph capillaries versus blood capillaries.

00:24 So i think it's going to be best to just discuss it and the different characteristics of each.

00:30 And then we can figure out which one is right.

00:32 So lymph, lymph node, you can think of.

00:40 It's not going to be the color of blood.

00:42 It's going to be colorless.

00:47 Blood capillary is going to be red.

00:55 Joined dead ends with artelials and then at the other end with the venules.

01:06 This one's going to be flying.

01:08 So close at the tip.

01:12 These are going to be a lot wider.

01:15 These are going to be narrower.

01:18 Just kind of think about what they're trying to transport.

01:21 And these can carry lymph.

01:24 These are going to be carrying.

01:30 So now that we know that, it's talking about what are the differences.

01:36 And we have five options, abc, d, and e.

01:43 Let's use red.

01:46 Let's go through which one is right.

01:49 So lymph capillates larger in diameter than blood capillaries.

01:52 That's true...
