3) It carries out immune responses directed against particular microbes or abnormal cells. 2. Locate each of the following lymphatic vessels: right lymphatic duct, thoracic (left lymphatic) duct, right and left subclavian veins, and cisterna chyli. a. Right lymphatic duct b. Thoracic (left lymphatic) duct c. Right and left subclavian veins d. Cisterna chyli .
The muscle fibers contain many myofibrils, which are the parts of the fiber that actually contracts | Part B: Epithelial Histology Based on shape, identify the three types of epithelial tissues and provide a description of each: Epithelial Tissue Type | Description | Squamous | single layer of flat cells; scale like | Cuboidal | single layer of cubed shaped cells | Columnar | tall, column-shaped | Identify where each of the following types of epithelial tissues are found: Epithelial Tissue Type | Location | Simple squamous | found in lungs and kidneys | Simple cuboidal | Is found covering the kidneys, lining the kidneys tubule, and lining some glandular ducts. | Simple columnar | lines most of the gastrointestinal tract | Stratified squamous | lining of mouth, esophagus, anus, and vagina | Stratified cuboidal | is found in the larger ducts of the mammary glands, sweat glands, salivary glands, and pancreas | Stratified columnar | is found in the vas deferens, part of the male urethra, and
(5 points) 1. The epithelial tissue covers the surfaces of the body whether external or internal. It works as a protective covering or boundary for these surfaces. It includes the outer layer of skin, as well as the inter surface of “hollow” organs like stomach, colon, and blood vessels. 2.
This could be in the form of a liquid, like blood. The matrix is usually secreted by connective tissues. There are connective tissues in blood, cartilage, bone, areolar tissues and adipose tissues. The blood transports materials, areolar gives support to the tissue, and as does cartilage, the bone strengthens and protects. Many different tissues are made of different fibres which are secreted by the cell to provide characteristics.
7. A distinctive feature of eukaryotes is the organization of their chromosomal DNA which is tightly packaged with proteins into a membrane-bound structure called a _______. 8. The delivery system of eukaryotic cells called the ______ complex can collect, package, modify, and transport molecules. 9.
Also it is common in the liver cells, striated muscle and nerve cells. Golgi apparatus: Golgi apparatus is usually connected to the endoplasmic reticulum (ER). It stores and transports proteins and other substances manufactured by the ER. Golgi apparatus is made up of several folds of membranes and a collection of vesicles. The number of Golgi bodies in a cell varies according to its function.
The cell body, also called the soma, contains the nucleus, cytoplasm, and other organelles. It manages the metabolic activity of the neuron. The axon is a thin cytoplasmic projection that extends from the cell body. It transmits impulses from the cell body to another nearby neuron. At its end, it may branch off in order to transmit impulses to dendrites.
And Inguinal lymph nodes are located in the groin area, these also may be superficial or deep lymph nodes. The major functions of lymph nodes are to remove foreign materials which are extracted from the lymph and deposited here. They store lymphocytes, type of white blood cell and releases them when necessary. There are two types of lymphocytes, T-cell and B-cell lymphocytes. T-cells destroy foreign substances directly or indirectly by releasing various substances.
Several molecules make matter - organelles. Organelles metabolized and work together to make cells. Cells make tissues and a minimum of 2 tissues, usually four types make an organ. The organs work together in certain organ systems. Multiple organ systems make the organism.
