4 Basic Tissue Types

Epithelial, Connective, Muscle, Nervous.

Epithelial Tissue

A type of tissue that covers body surfaces, and organs. It protects and absorbs. Tightly packed cells that lines the body.

Connective Tissue

A body tissue that provides support for the body and connects all of its parts. Made of fibers and cells that is found between other tissues.

Nervous Tissue

A body tissue that gives information throughout the body back and forth. Found in brain, spinal cord and nerves.

Muscular Tissue

A tissue that helps pump blood, supporting movement, lifting heavy weights and giving birth. It is made up of muscle fibers that can contract and relax. Found all throughout body such as intestines, liver, pancreas.

Simple Squamous

Single layer of flattened cells. It protects, filters, and transports. Found in kidneys, lungs, and blood vessels.

Simple Cuboidal

A single layer of cube-shaped cells that functions in secretion and absorption. Found in ducts of kidneys, pancreas, and salivary glands.

Simple columnar

A single layer of tall, column-shaped cells that absorbs nutrients and secretes mucus. Found in the digestive tract and respiratory system.

Stratified Squamous

Tissue of multiple layers of flattened cells that provides protection against abrasion and infection. It is found in areas such as the skin, mouth, and esophagus.

Hyaline Cartilage

Found at the ends of your bones and in nose. Helps your bones move smoothly past each other in your joints. It is fibers made up of Type II collagen.

Compact Bone

Forms a hard, dense, outer layer of bones throughout the human body. It provides support and strength to bones. Found under the periosteum and in the diaphyses of long bones.

Blood

A body fluid that contains, plasma, red blood cells, white blood cells and platelets. It helps transporting oxygen and nutrients to the lungs and tissues, and forming blood clots to prevent excess blood loss. Its located throughout the body.

Aeolar Tissue

A connective tissue is found throughout the whole body. It provides support and helps to protect organs, muscles, and many other tissues. It also helps to bind the skin together. Made up of fibers and cells that are “glued together” by water, proteins and carbohydrates.

Adipose Tissue

A connective tissue thats found underneath your skin between organs and bone marrow. Its the energy storage system. It provides energy storage, insulation from extreme temperatures and cushioning around soft organs. Its a simple structure composed of a single fat molecule and a few cellular organelles.

Dense regular connective tissue

A type of tissue that is mostly made up of tough protein fibers called collagen and cells called fibroblasts. Dense connective tissue supports, protects, and holds bones, muscles, and other tissues and organs in place. Made of tightly packed collegen fibers. Found in tendons and, ligaments.

Dense irregular connective tissue

A tissue that provide strength and support and is found in the dermis of the skin and joints. Its densely packed, and has collagen fibers allowing for flexibility while having strength.

Cardiac Muscle

It makes the thick middle layer of the heart. It’s made up of branched, striated cells and pumps blood throughout the body.

Skeletal Muscle

It produces movement, sustain body posture and position, maintain body temperature, store nutrients, and stabilize joints. Found throughout the body and attached to bones and tendons. Its thousands of muscle fibers wrapped together by connective tissue.

Smooth Muscle

A muscle that is made up of long thin cells with a single nucleus. Found in hollow organs (bladder and blood vessel.) Controls the involuntary movement of most organs present in the body. (Digestion, maintains blood pressure and flow).

Compare and Contrast Pos and Neg feedback

positive feedback makes a change in the body's condition, pushing it further away from its set point, while negative feedback counteracts a change, bringing the body back to its normal state Negative feedback example- body temp regulation (sweating when hot, shivering when too cold). Positive feedback example- Childbirth.

what connective tissue proper, cartilage, bone, and blood have in common that makes them all connective tissue

they are composed of cells embedded within an extracellular matrix, which is a ground substance containing protein fibers, allowing them to connect and support other tissues throughout the body; despite their varied functions, this shared matrix is what defines them as connective tissue

2 blood types and their functions

red blood cells (erythrocytes), which carry oxygen throughout the body, and white blood cells (leukocytes), which fight infection by defending the body against foreign substances like bacteria and viruses. 

Blood components

plasma (the liquid part), red blood cells (erythrocytes), white blood cells (leukocytes), and platelets (thrombocytes); where red blood cells carry oxygen, white blood cells fight infection, and platelets help with blood clotting, all suspended within the plasma fluid

givin a picture of a muscle, identify if its skelatal, smooth or cardac

Homeostasis

the ability of an organism to maintain a relatively constant internal environment despite changes in the external conditions. Essentially, it's the body's ability to keep internal conditions stable, like temperature and fluid balance, within a set range, even when faced with external changes. . Examples- Temperature, blood glucose levels, and hormones
