What else can I help you with?
What occurs during gas exchange?
External Respiration is where gasses are absorbed into the blood through the alveolar capillary beds. Internal respiration is where the gasses are transferred into the cells from the blood.
What percentage of water is in red blood cells?
there is 43% of water in the red blood cells
What happens to blood cells when they loose water?
When blood cells lose water, they shrink and become more concentrated in solutes. This can impair their ability to function properly, including gas exchange and nutrient transport. Severe dehydration can lead to reduced blood volume and affect overall circulation in the body.
What has a higher percentage blood or water in the body?
Water As blood is made from water and blood cells.
What is the making of blood cells?
Water is the biggest "substance" in making blood. Blood is about 97% water.
Brad placed a drop of blood in some distilled water. What happened in the red blood cells?
When Brad placed a drop of blood in distilled water, the red blood cells experienced a process called osmosis. Since the distilled water is hypotonic compared to the intracellular fluid of the red blood cells, water entered the cells, causing them to swell. If enough water enters, the cells may eventually burst in a process known as hemolysis.
Is pure water hypertonic to red blood cells?
Yes, pure water is hypotonic to red blood cells, meaning that it has a lower concentration of solutes compared to the inside of the cells. When placed in a hypotonic solution, red blood cells may take in water and potentially burst due to the influx of water.
How odes a fish get oxygen to its cells and get rid of metabolic wastes?
Fish obtain oxygen through their gills, where water flows over thin membranes rich in blood vessels. Oxygen diffuses from the water into the blood, while carbon dioxide, a metabolic waste, diffuses from the blood into the water to be expelled. This efficient gas exchange allows fish to supply their cells with oxygen and remove wastes continuously as they swim.
What is the Water that is found in the space between cells and blood vessels?
The water found in the space between cells and blood vessels is known as interstitial fluid. This fluid serves as a medium for the exchange of nutrients, gases, and waste products between blood and cells. It plays a crucial role in maintaining tissue hydration and homeostasis, as well as facilitating cellular communication. Interstitial fluid is a key component of the extracellular fluid compartment in the body.
Countercurrent exchange in the fish gill helps to maximize what?
Countercurrent exchange in the fish gill helps to maximize the diffusion of oxygen from the water into the blood and the removal of carbon dioxide from the blood into the water. This efficient exchange occurs due to the flow of water and blood in opposite directions, creating a concentration gradient that allows for more effective gas exchange.
Would osmosis have a higher concentration of water molecules distilled water or red blood cells?
Distilled water would have a higher concentration of water molecules compared to red blood cells. Red blood cells have solutes dissolved in them, so they have a lower concentration of water molecules relative to distilled water. This concentration gradient would result in osmosis moving water into the red blood cells to equalize the concentrations.
What functions do the capillaries do in the cardiovascular system?
They enable the exchange of water, oxygen, carbon dioxide, and many other nutrient and waste chemical substances and between blood and surrounding tissues.
