what are the two major groups of cells types in the human body?

CHAPTER 6 Meiosis and Mendel Your body is made of two basic cell types. One basic type are somatic cells, also called body cells, which make up almost all of your tissues and organs. The second basic type are germ cells, which are located in your reproductive organs.

Pluripotent cells can give rise to all of the cell types that make up the body; embryonic stem cells are considered pluripotent. Multipotent cells can develop into more than one cell type, but are more limited than pluripotent cells; adult stem cells and cord blood stem cells are considered multipotent.

There are two types of neural cells, neurons and neuroglia. Neurons, approximately 86 billion of which are contained in a human brain, transmit electrical and chemical signals to one another. Neuroglia, also known as glia, support and protect neurons.

A living thing can be composed of either one cell or many cells. There are two broad categories of cells: prokaryotic and eukaryotic cells.

Cells are the basic structural and functional unit of all life. Examples include red blood cells and nerve cells. Tissues. Tissues are groups of cells that share a common structure and function and work together.
408776
There are two major types of lymphocyte: B lymphocytes, which mature in the bone marrow; and T lymphocytes, which mature in the thymus. The bone marrow and thymus are thus known as the central or primary lymphoid organs.

All living things can be divided into two types of cells: prokaryotes and eukaryotes. Eukaryotic cells have a nucleus and other cell structures that are bound by a distinct membrane. Bacteria, as prokaryotic cells, lack these internal membrane-bound structures.

The five main types of blood cells are basophils, neutrophils, eosinophils, monocytes, and lymphocytes. Basophils are the cells mainly responsible for allergic reactions. They defend against parasites and bacteria by excreting two chemicals: heparin and histamine. Heparin is a blood-thinning substance.

The two major categories of body membranes epithelial and connective tissue- are classified in part according to their tissue makeup. The epithelial membranes include the cutaneous membrane (skin), the mucous membranes, and the serous membranes (Figure 4.1).
1471492
There are mainly two types of stem cells: embryonic stem cells, which are derived from embryos, and somatic or adult stem cells, which are undifferentiated cells residing in a tissue or organ along with other differentiated cells (somatic cells).
883799
There are four main types of tissue: muscle, epithelial, connective and nervous. Each is made of specialized cells that are grouped together according to structure and function. Muscle is found throughout the body and even includes organs such as the heart. Our outer layer of skin is epithelial tissue.

All three cell types form in the bone marrow, which is the soft tissue inside your bones. Red blood cells transport oxygen to your body's organs and tissues. White blood cells help your body fight infections. Platelets help your blood to clot.

The human body contains more than 200 types of cells that can all be classified into four types of tissues: epithelial, connective, muscle, and nervous. Epithelial tissues act as coverings controlling the movement of materials across the surface.

All the parts of your body are made up of cells. There is no such thing as a typical cell. ... In humans, there are about 200 different types of cells, and within these cells there are about 20 different types of structures or organelles. All cells have a membrane.
271868
All cells are classified into two broad categories - Eukaryotes and Prokaryotes – with Bacteria, along with the domain Archaea, falling under Prokaryotes.
842524
Nervous tissue is composed of two types of cells, neurons and glial cells. Neurons are the primary type of cell that most anyone associates with the nervous system. They are responsible for the sensory, integrative, and motor functions of the nervous system.

Peripheral blood mononuclear cells (PBMC) give selective responses to the immune system and are the major cells in the human body immunity. They contain several types of cells such as lymphocytes,monocytes or macrophages.
