The precursor of all lines of blood cells is the hemocytoblast.
The field lines have no start or stop. They form closed loops and can never cross. The field lines are found inside and outside the magnet. From the point of view looking from inside the magnet the field lines appear to be (say) S to N, while outside the lines appear to be N to S. ( you could choose the opposite convention) +-->---| S inside -->--------- N | --- outside-->-+ +-----------<-----------<-----------<---------------<-+
Cuban, Spanish, Jewish, Cherokee, German, & Irish...& I've been told there's some Polish blood lines in there somewhere as well... (^_^)
In latin, cell means compartment or little room. Robert Hooke discovered cells in cork (the bark of a particular tree). He observed small honeycomb-like structures. They reminded him of rooms. That is why he called them cells.

Insulators are commonly found in a variety of items, including electrical appliances, power lines, and circuit boards. They are used in materials like rubber, glass, and ceramic to prevent the flow of electricity and protect users from electric shock. Additionally, insulators can be found in thermal applications, such as in building materials and thermal clothing, to reduce heat transfer.
Animal cells. It lines some of your (human) intestines.
no because blood, nerve, bone, muscle, and the skin cells all look different. for example: blood cells look like tiny dots and muscle cells look like long stretchy lines
Epithelial cells appear flat and form a single layer that lines some organs and tissues in the body. They provide a protective barrier and can be found in areas such as the skin, blood vessels, and intestines.
Epithelial cells are found covering the body surfaces, including the skin, lining the inside of organs and blood vessels, and forming glands. They provide a protective barrier, regulate the exchange of substances, and secrete necessary fluids.
Blood is composed of red blood cells, white blood cells, platelets, and plasma. Red blood cells carry oxygen throughout the body, white blood cells help fight infections, platelets aid in blood clotting, and plasma is a fluid that carries these cells and other substances throughout the body.
"Primary acquired melanosis" refers to a condition where abnormal pigmented cells form on the conjunctiva (the membrane that lines the inside of the eyelids and covers the white part of the eye). It is more commonly found in older individuals and can sometimes be a precursor to melanoma. Treatment usually involves monitoring for changes and, in some cases, surgical removal.
They are called epithelial tissues. In air passage stratified epithelium is found
There are many blood lines. They can't be counted.
The epithelium is a type of tissue that lines the surfaces of organs and structures throughout the body, providing protection, absorption, and secretion functions. It can be found in areas such as the skin, respiratory tract, gastrointestinal tract, and blood vessels. Epithelial cells are closely packed together and can be classified based on their shape and layers.
No, the endothelium itself does not have one-way valves. The endothelium is a thin layer of cells that lines blood vessels and is involved in regulating vascular functions. One-way valves are typically found in veins, particularly in the limbs, to prevent backflow of blood. These valves work in conjunction with the muscular actions of the surrounding tissues to facilitate blood flow toward the heart.
The blood-facing membrane of epithelial cells is known as the endothelium. It lines blood vessels and forms a barrier between the blood and surrounding tissues. The endothelium is crucial for regulating the transportation of substances in and out of the bloodstream.
A single red blood cell lasts about 100-120 days before it is consumed by macrophages and recycled. These cells are so abundant in the human body that about 2.4 million new red blood cells are produced every second in the bone marrow.
