  2. Erythropoiesis - Wikipedia

    en.wikipedia.org/wiki/Erythropoiesis

    A feedback loop involving erythropoietin helps regulate the process of erythropoiesis so that, in non-disease states, the production of red blood cells is equal to the destruction of red blood cells and the red blood cell number is sufficient to sustain adequate tissue oxygen levels but not so high as to cause sludging, thrombosis, or stroke ...

  3. Erythrocyte rosetting - Wikipedia

    en.wikipedia.org/wiki/Erythrocyte_rosetting

    Erythrocyte rosetting or E-rosetting is a phenomenon seen through a microscope where red blood cells (erythrocytes) are arranged around a central cell to form a cluster that looks like a flower. The red blood cells surrounding the cell form the petal, while the central cell forms the stigma of the flower shape.

  4. Blood cell - Wikipedia

    en.wikipedia.org/wiki/Blood_cell

    Hemoglobin is an iron-containing protein that gives red blood cells their color and facilitates transportation of oxygen from the lungs to tissues and carbon dioxide from tissues to the lungs to be exhaled. [3] Red blood cells are the most abundant cell in the blood, accounting for about 40-45% of its volume.

  5. Vascular tissue - Wikipedia

    en.wikipedia.org/wiki/Vascular_tissue

    As the plant grows, new vascular tissue differentiates in the growing tips of the plant. The new tissue is aligned with existing vascular tissue, maintaining its connection throughout the plant. The vascular tissue in plants is arranged in long, discrete strands called vascular bundles. These bundles include both xylem and phloem, as well as ...

  6. File:Simple diagram of plant cell (numbers).svg - Wikipedia

    en.wikipedia.org/wiki/File:Simple_diagram_of...

    English: A simple diagram of a plant leaf cell, labelled with numbers. It shows the cytoplasm, nucleus, cell membrane, cell wall, mitochondria, permanent vacuole, and chloroplasts. Note going down the left the numbers are not sequential, this is to match the numbering on others in the series.

  7. Plant anatomy - Wikipedia

    en.wikipedia.org/wiki/Plant_anatomy

    Chloroplasts in leaf cells of the moss Mnium stellare. Plant anatomy or phytotomy is the general term for the study of the internal structure of plants.Originally, it included plant morphology, the description of the physical form and external structure of plants, but since the mid-20th century, plant anatomy has been considered a separate field referring only to internal plant structure.

  8. Akaryocyte - Wikipedia

    en.wikipedia.org/wiki/Akaryocyte

    Overall, there are four main types of akaryocytes discovered: Erythrocytes, commonly known as red blood cells, are concave-shaped cells responsible for gas exchange, and the transfer of nutrients throughout an organism. Red blood cells are classified as akaryocytes because they lack a cell nucleus after they have fully developed.

  9. Red blood cell - Wikipedia

    en.wikipedia.org/wiki/Red_blood_cell

    Red blood cells (RBCs), referred to as erythrocytes (from Ancient Greek erythros 'red' and kytos 'hollow vessel', with -cyte translated as 'cell' in modern usage) in academia and medical publishing, also known as red cells, [1] erythroid cells, and rarely haematids, are the most common type of blood cell and the vertebrate's principal means of delivering oxygen (O 2) to the body tissues—via ...
