B cells and t cells both originate from stem cells in the?
B cells and T cells both originate from the haematopoietic (or hematopoietic) stem cells located in the bone marrow. T cells mature in the thymus. B cells mature in the secondary lymphoid tissues (such as the spleen).
Which kind of cells mostly found in lymph?
In the medullary cords = plasma cells & B Cells In the medullary sinus = macrophages B cells and T cells freely float around in all lymph nodes and lymph organs.
Lymph node that contain t cells and b cells?
T-cells and B-cells are both initially made in the bone marrow. T-cells mature in the thymus. They both freely float around in all lymph nodes and the various lymph organs (e.g., tonsils, spleen...).
What statement regarding stem cells is false a. they form totipotent embryo b. can be induced to form tissues c. they are undifferentiated?
dsad
What is the difference between cell and tissue?
Isn't it obvious? Cells are places in prisons where they keep prisoners, or people that have done something wrong, and tissues are a substance of material that you blow your nose in when you have a cold.I would have thought that obvious to everyone!Cells are a jelly-like substance inside us humans. They are the CORE of us humans. When we are a nucleas inside our mothers womb, we are made up of only stem cells. Now, stem cells are extremly special, as they can change into any other cell in your body. So, what happens is, when you start developing, some of these cells change into brains cells, some into blood cells, or maybe skin cells, and if you're a boy, sperm cells also. We have millions of cells inside us.As for tissues, it's easy to understand as long as you understand the cells. Tissues are a group of the same cells. Once again, we have millions of TISSUES inside us. These are extremly important, as without these, our whole body wouldn't work.I know you didn't ask for more than that, but I'll give you more...Onto Organs: Organs can't work alone, can they? Your heart wouldn't work without the blood cells, (blood), as the heart would have nothing to pump around. But Organs also can't work without other Organs. Taking the heart for another example, the heart wouldn't work without the lungs, because lungs help us breathe, helping the heart pump. The brain is also an Organ, and without it, NONE of us would work, as when the brain shuts down, so does our WHOLE body.So, to make our body work, we have to have Organ Systems. Like the digestive system. That is a group of Organs working together to digest our food.I hope I helped you. And remember, I'm only eleven! I would like to thank Mr Shufflebotham for teaching me this, and I want to say HI to Molly F, Jack G, George S, Jack D, Oscar B, and of course, ME! Hehe!
How are organs and tissues similar?
they are similar because organs are made out of tissues so they work together to perform a specific function. hope I helped! B
Is the smallest unit that forms the living being?
atom. b/c when atoms are combined they make molecules and when they combine they form cells and then tissues then organs and then system and then a living organism is formed
How are tissues organs and organ systems alike and different?
Tissues are made up of "like" cells that perform a specific function. Organs are tissues that act together to perform a specific function or functions. Organ systems are a group of organs acting together to perform a function or set of functions. All perform a function or functions but the level of complexity and the number of functions increases as the complexity increases.
What is a major function of the skeletal system?
Support, protection, movement, shape, and red blood cells
B cells and t cells both originate from stem cells in the?
B cells and T cells both originate from the haematopoietic (or hematopoietic) stem cells located in the bone marrow. T cells mature in the thymus. B cells mature in the secondary lymphoid tissues (such as the spleen).
Which of these is most inclusive level of organization listed here is an a. organ b. atom c. molecule d. multicelled organism e. cell?
Organ, since it is composed if cells, tissues, molecule, and multi-celled organisms. Multi-celled organisms are only composed of one then one cell.
Which kind of cells mostly found in lymph?
In the medullary cords = plasma cells & B Cells In the medullary sinus = macrophages B cells and T cells freely float around in all lymph nodes and lymph organs.
What are the tissues of the immune system?
The lymphatic tissues, white blood cells, the cells of Langerhans, B-cells, T-cells, tonsils, lymph nodes, pancreas, bone marrow, mast cells, wandering lymphocytes, wandering macrophages, type I lung cells and quite a few other types
What has the author A J B Kirk written?
A. J. B. Kirk has written: 'A manual of cardiopulmonary transplantation' -- subject(s): Cardiopulmonary Bypass, Handbooks, manuals, Transplantation of organs, tissues
Lymph node that contain t cells and b cells?
T-cells and B-cells are both initially made in the bone marrow. T-cells mature in the thymus. They both freely float around in all lymph nodes and the various lymph organs (e.g., tonsils, spleen...).
What statement regarding stem cells is false a. they form totipotent embryo b. can be induced to form tissues c. they are undifferentiated?
dsad
Where are T and B cells found?
In the blood and mainly in secondary lymphoid tissues such as the spleen and lymph nodes.
