Missing words in the text

Hello, my homework is to listen this video on youtube: and I will write some test from it. But I don´t understand several words in the text. Please, could anyone listen it and write these words? I rewrote the text and where I´m not sure or I really don´t know, I wrote it in the brackets and added question marks:

Thanks for all replies.

The objective of targeted cancer therapy is to deliver chemotherapeutics directly to the cancer tissues (for???) minimizing undiserable toxicity
to the rest of the body. Nanoparticle formulation begins (at???) the solution of drug and polymer molecules in an organic solvent. The
blue spheres represent an anticancer chemotherapeutic agent (and???) the white strands represent diblock copolymers which are realistically more
flexible than shown here. A diblock copolymer is composed of two joint polymer chains. A hydrofilic or water-loving block shown in blue and hydrofobic
or (water-fearing???) block shown in orange. Nanoparticle formation is accomplished by the (drop...???) addition of the organic solution to rapidly stirred water. The
initially disordered copolymers rapidly self-assemble at the organic-water interface of the nanodroplets reorienting themselves
so that the hydrofobic block is rounded and (s...???) by the hydrofilic blocks. This polymer (....???) can be subsequently surface-modified
with various cancer targeting ligands such as antibodies or small molecules. The nanoparticle solution can than be modified
into form to (allow the???) intravenous administration. The nanoparticles are quickly distributed througout the body by the circulatory
system (with which???) they are also delivered to the site of the (tumor???). One hundred times smaller than red blood cells, nanoparticles
posess the unique ability to permeate through the (leaky walls of tumor vasculiture???) which are formed during the process of tumor growth. Through this
passive targeting technique the nanoparticles can be concentrated within the tumor tissue. On the cancer cell´s surface membrane the
nanoparticles encounter surface receptor molecules - microscopic markers expressed on caner cells but not expressed by normal tissues.
The nanoparticles targeting ligands bind specifically to these receptors triggering a response also known as receptor-mediated
endocytosis which (...???) the nanoparticles into the cancer cell. This process enables thousands of nanoparticles to enter (into???) each
of the targeted cancer cells. Inside the cell the nanoparticles are enveloped (into???) endosomes. These endosomes merge to form larger
endosomes or eventually lysosomes -the digestive (stomachs???) of cells. The anticancer drugs can be released in a controlled mannner
by the degradation of the polymer nanopartical shell, the highly toxic chemotherapy can thus be delivered directly at the
site ( ....???) without affecting other body systems. Typically the drugs will cause the cancer cells undergo apoptosis or
programmed cell death. This nanoparticle therapy can eventually lead to the eradication of the (tumor...???)
